Title: A band-compressed television signal transmission system
Inventor: SHIMAMURA TADAO
IPC: H03M7/00
Filed: 1969-08-08
Abstract: 1,269,693. Television. NIPPON ELECTRIC CO. Ltd. 8 Aug., 1969 [8 Aug., 1968], No. 39889/69. Heading H4F. A band-compressed television transmission system comprises a delta modulator which is unable to follow fast variations in the video signal and a further pulse modulator the output of which represents the fast variations. As shown, Fig. 2, the delta modulator comprises a one-bit coder 11 with a feedback path comprising an integrating decoder 12 and a subtractor 13 to which the video input signal 101 is also applied to generate a difference signal 103 which forms the input to the coder 11. The output 104 produced by the coder 11 depends on the polarity of the difference signal which is sampled under control of a clock input (not shown). The clock frequency and the modulator quantizing step are selected so that the output signal has a low bandwidth and closely follows slow variations in the input signal, but this results in the modulator being unable to follow fast variations in the input signal. These fast variations result in a large difference signal 103 at the output of subtractor 13 and this is applied as the input of a second delta modulator controlled by the same clock frequency but having a larger quantizing step. The output 204 of this second modulator represents the fast variations of the input signal. The two modulator outputs 104, 204 are combined in a time division multiplexer 14 to produce a signal 001 which is transmitted to a receiver comprising a demultiplexer 16 and two demodulators 15, 25 the outputs 106, 206 of which are combined in adder 17 to reconstitute the video signal. The clock frequencies of the two delta modulators need not be the same, the second delta modulator may be replaced by a pulse code modulator, and the modulator outputs may also be transmitted on a frequency division or space division basis.

Title: A sorption vacuum pump
IPC: H01J9/38
Filed: 1961-11-08
Abstract: 1,003,126. Diffusion pumps; high vacuum pumps. MAX-PLANCK-GESELLSCHAFT ZUR FORDERUNG DER WISSENSCHAFTEN E.V. Nov. 8, 1961 [Nov. 8, 1960], No. 39980/61. Headings F1E and FIN. A process for creating a very high vacuum comprises absorbing the gas molecules to be removed in an absorbing medium in a high vacuum chamber, conducting the medium to a chamber having a lower vacuum where the molecules are desorbed, wherein the medium is introduced into the high vacuum chamber in the form of a mist of fine droplets or wet vapour. In one form of the apparatus for carrying out the method, Fig. 1, the sorbing medium is introduced into a vessel 1, connected by a pipe 2 to the vessel being exhausted, by spraying from a jet 3, the medium impinging upon a projection 101 in the vacuum vessel so that a uniform liquid film is formed which descends along the side wall of the chamber, the interior of the vessel being filled with a fine mist of droplets. The large surface area presented by the medium readily absorbs gas molecules, and the gas laden medium collects in the lower portion of the vessel, where a siphon 6 removes the medium to a further vessel 7 in which the gas is freed from the liquid. Alternatively, vaporised sorbing medium may be introduced in the vessel I, and the jet 3 cooled to produce a mixture of vapour and droplets, which then impinges upon a cooled vessel chamber. The vapour may be ionised by any known method, e.g. induction heating, arc or glow discharge, and mercury or an organic liquid having a low vapour pressure may be used as the sorbing medium. The vessel 7 is evacuated by connecting to, e.g. a diffusion pump, and apparatus is described, Fig. 3 and Figs. 5 and 7 (not shown), in which a diffusion pump is made integral with the high vacuum chamber and is constituted by guides 14, 23, 25. Alternatively, Fig. 4a, the backing vacuum is obtained with the use of a turbomolecular pump.

Abstract: 1,221,137. Photographic silver halide emulsions. ILFORD Ltd. Aug. 20, 1969 [Aug.21, 1968], No.40026/68. Heading G2C. A process for the production of a photographic colloid silver halide emulsion comprises forming the silver halide grains in the presence of a metal chelating agent which is diethylene triamine- N, N ,  N<SP>1</SP>, N<SP>11</SP>, N<SP>11</SP>-penta-acetic acid, triethylene tetramine-N; N ,  N1 ,  N<SP>11</SP>, N<SP>111</SP>, N<SP>111</SP>-hexa-acetic acid or 1, 2-diaminocydohexane-N, N, N<SP>1</SP>, N<SP>1</SP>- tetra-acetic acid. Preferably at least 3g. of the said chelating agent per gram mol of silver is present during the formation of the silver halide grains. The silver halide emulsions of the present invention have enhanced light-sensitivity. However if the chelating agent is added at a later stage in the emulsion making process no sensitivity enhancement of the resulting silver halide emulsion is obtained. Specification 1, 221, 138 discloses a process for the production of a photographic emulsion having a reduced tendency to develop desensitized spots due to inclusions in the emulsion, whichcomprises adding to the emulsion, after the chemical sensitization of the emulsion, but before it is coated on a support to form a photographic material, a metal chelating agent as defined above.
